I just received this litter box and am extremely disappointed in the shape of the box.  When I researched the item and saw the shape of the litter box, I was sold on the fact that it had a "cornered" back end (not square).  It was the main reason for purchasing this item.  As a matter of fact, I was going to purchase two of them, but decided to see if my cat liked it.  Now there is no point, as this litter box does not fit into a corner.

If you click on the product listing, you will see that there are two views that show this box as having a "cornered" back side.

The product that I received has a square back side.  Not what I wanted.
